To 'all 'whom it may concern.' Y

Be it known that I, JAMES H. WAGEN- Hons'r, a citizen of the United States, resid-y ing in the city of Akron, county of Summit, and State of Ohio, have invented certain new'and useful "Improvements in Vehicle- Wheel Rims, of which thefollowing is a specification.

My invention relates particularly to that type of rim which is Agenerally known as a .,demountable rim, that is, a wheel structure having a removable rim capable of carryin a fully inflated tire, and `means for detacha ly,mounting the same upon the wheel structure.

In the accom anying drawings which forma part of tliis specification, Figure 1 is a sideelevation of a portionv of a vehicle wheel equipped with my improved device; F-ig. 2 is a transverse sectional View on-line II-II of Figrl ;V Fig. 3 is atransverse Sectional vieW througha felly, rim and tire showing afmodifed form of my device; Fig.l `4. is a view similar to Fig. 2 showing one of the retaining clips for locking t e tire carrying rim uponA the wheel moved into inoperative position; Fig. 5 is a perspective view of this cli Fig. 6 is a perspective View of a modi ed form of clip shown jii Fig. 3; Fig.- 7 is a perspective view of al flanged retaining member mounted on' the opposite side of the 4felly from the clips F.ig.-8 is a perspective view 0f a 'special form of Washer; Fig. 9 is a perspective View of a form of bolt particularly adapted for use in my improvedV structure; Fig. 10'i`sV a View similar 'to Fig.`1 showing a side ele vation of Fig. 4; Fig. l11v is. @transverse sectional view pf a telly, rimand tire showing a furthe| f modified form of retaining.

'Referring tothe drawings in detail. the numeral 1 designates the felly of av'ehicle wheel, to which ispermanently secured, by shrinking or in any" other suitable manner, 'the allyband el which is provided a asV the same direction and which form frusta of concentric cones. Mounted upon this felly band'is a removable tire-carrying rim 5 supporting the tire 6. This rim may be of eitherkthe quick-detachable or clcncher type. Its base is shown provided with the depressed portions 7 and 8 adapted to seatupon the flanges 3 and/1, respectively. The wheel is equipped at equally spaced intervals about its periphery with means for securing the tire-carrying rim in place upon the felly band. Each of these means comprises a bolt l 9 passing laterally through the telly, and through a washerl() at one side of the felly and a clip l1" at the other' side, this clip being provided with an outwardly exmnding y"hooked flange 12 adapteduto engage the flange 3 and support the same, as shown in Eig. 2. At oneendof the bolt is a faced head portion4 13 between which and the shaft of the bolt is anexternally threaded section tion adjacent to the hooked extension is made substantially fiat, as shown at 18. Adjacent v14, upon which is adapted to be mounted a4 tothis surface d extendingfrom the body portionV is a lug 19 which may incertainconstructions enter a socket20 inthe felly when the. clip is in the operative'position, shown in Fig. 2.V .The Vportion .of the bolt remote from that which supports the clip 15 is externally Vthreaded'vat 21, the 'metal of the bolt being faced at and 23-tol form two flat sides. Thisthrcaded section" of the bolt passes 'througha washerl 2li-,hav-

,ping a rectangular opening '25whose lesser A.

dimension lis smallerthan the diameterof the bolt.V This Washer may be circular in shape or may bef-formed as shown in'Fig. 8, with `the ltwo extensions 26- and 27; The" threaded end of the-bolt also .carries a mit 28, and when thewasher of the type. shown p in Fig. 8 is used, the extensions 261 andf27' are'bent'down, 'as shownA in Fig. 2, to ein;

brace opposite `faces of the nut, so that there. can'be no relative turningbetwe'en thenut andthe bolt after the former 4is once inlz place. I do not, ho-'weven regard the use' f of -theextensions 2,6v fand 27 asrequisite,but

fili

tions shown in Fig. 2, the rotation of the -bolt bv means of applying a wrench to the cause the clip to swing inwardly toward the center of the wheel, into substantially the position Shown in Fig. 10, thus permitting the tire-carrying rim and tire to be removed as a unit -from the wheel.

Whenl it-is desired to mount a tire. and rim upon the wheel, the removable riin is placed with the depressed portions 7 and 8 lightly resting a ainst the aiiges 8 and 4. By rotating the olt in the opposite direction from that which canses the `release of the clip from .the rini, the clip will rotate until the extension 19 engages the underportion of the flange 4. Further rotation of the bolt will then cause the clip to move laterally toward the rim until the hooked portion 17 engages the edge of the tirecarrying rim and the edge 29 ofthe -face 18 simultaneously passes under the edge of the flange 4:. The clip will then begin to` exert a double influence upon the tire-carrying rim. As the clip is forced toward the felly it will carry with it the 'rim and move the depressedl portions 7 and 8 laterally, forcing i inwardly toward the center of the wheel is .them to ride 'higher and higher upon lthe inclined flanges 3 and 4, thereby locking the tire-carrying rim securely| upon the felly band. At the same time the clip prevents the edge of the rim Which it engages from progressing radially outward away'fron'i the centerof the wheel and thus oliviates the tendency of the vremovable rim and 'tire to tilt with respect to the felly bandy whenthe rim is forced home upon the' ifellyband. This tendency, when therim is forced home by means 'of keepers exerting only a lateral pressure upon the rim, is liable to result in distortion of the tire tread and an unequal wearin'gof the tire, "besides producing eccentric strains witliii'the rim and `its associated parts. However, not only does the hooked portion of the clip restrain-'the edge 4of the rim from progressing radially. away from the felly band, but it also impresses-a force upon tlieedge of the rim obliqu'ely'ine ward, whicli'actu'ally tends to'd'rawthe riiu laterally and inwardly toward the center ofthc wheel, thus clamping the rim firmly in place. The drag on the edge of the rini made 'possible to` some extent by the slight canting of the clipoir the bolt as shown in Fig.v 17, e., tilting of the clip in a` plane perpendicular to the wheel, which results from the portion of the clip in engagement with ,the rini advancing more slowly, toward .the wheel than does` the part engaging the action between the surfaces 30, 31, and this reaction may be the sole or principal resultant of the axial movement of the bolt,.

tendingto cause inward radial clamping of the rim'agaiiist its seat, as hereinafter described in connection with Fig. 1G. The rim-engaging portion of the clip thus travels radially inward as well as laterally of the wheel, and drags the rim with it. F urtlierii'iore, it will be evident that the force which acts to diaw the rim toward the center of the wheel cooperates with the collapsing pressure of the inflated tire.

The engagement of the bottoni 'of the Harige l .with the surface 1.8 reduces the strain .upon the threaded portion of the bolt carrying the clip. When a structure suoli as that shown is used, the clip inove's toward the felly smoothly and without excessive lateral strain upon the bolt, z'. e., pull in the direction of the clip, at the saine tinie forcing the seats of the tire-carrying rim against their respective flanges.

Fig. 3 I have shown a modification iii which the face 18 is replaced by a wedge surface 3() engaging the inclined edge 31 of the flange Ll. on the felly band. In this type the rectangular lug 19 is replaced -b'v the circular lug 3:2. The operation of this yform is'sii'nilaiito that of the structure shown in Fig. 2, except that the fulcrumingfoi'ce aot- 'ing upon the member 17 is greaterbecause of the engagement of the wedging surfaces instead -of the surfaces parall'. to th'e axis of the bolt, as in the case of the rim shown in Fig; 2. In Fig. 3 I have also shown a plain washer .33 in lplace of the washer '24 having the extensions 26 and 27 illustrated iii Figs. 2 and 8. It Willbe apparent that 'when suoli a washer is used it will necesis received from engagement of the clip with the tire-carrying .rim itself, instead of with a fix'ed portion of the wheel, asin the forms already described, but this forni does not`involve the drawing inwardly of the riin.

against its seat by wedging reaction or by tilting of the clip,` or both. In this type the clip :oniprises a. hooked portion 34 engaging I our 'edge of the tire-carrying riinfand abody l portion 35 adapted to be mounted upon a bolt 3G permanently secured to and passing through the telly l. he mounted on the tlire'aded end 38 of the bolt is used 'for forcing the clip towardlt-lie telly of the wheel. ln this type?, instead of providing` a bearing surface on 'thev lower' part of the flange l of the telly band Iwith v which the` clip'niay engage, I provide'a long,

substantially horizontal bearing surface 39 Vnecessary for the rim itself to yield between' i adjacent to the hooked ortion of the clip and adapted to seat solidly against the portion of the-tire-carryin rim adjacent to the flange which is grippe by 'the'hooked portion of the clip. It will be seen that because of this lon bearing surface and over-hang,l there is little eccentric or lateral strain brought upon the bolt, since in order for the clip to swing about an axis perpendicular to the plane of the drawing-,Nit will be "the point 4 0 and the extreme eiige, something which is substantiallyimpossible becauseof the stiffness of the rim in this plane afforded by the inturned flange of the rim.

In"'F-igs.l i 12 and 13 I have illustrated a modification in whih a keeper 41 is used that does, not project beneath the felly band, nor has it a long bearing surface adapted to support Athe lwer surface of the rim, as-in the' case of the structure shown i'n Fig. 11. F1 L 12 and 13 illustrate one of the simplest emsodiments of my invention. .The 'clip or keeper 41 is `provided with a body portion 42, .from which extends the hooked member 43 'overlying the edge ofthe detachable rim to such an` extent that the clip may tilt or cant upon the bolt 44 through an appreciable ngle4 withoutireleasing the edge of the rim.

n Figs be fixed'to the felly and has lits end threaded at 45 to engage a 'nut46 which retains the order to permit the tilting or canting of .the clip, in this form as well as inthe types previously described, the clip is designed to fit loosely upon its retaining member. `This mayl beaccomplshed inthe' pre-` ceding foi-ms by a .loose fitting 'of the threads, or in the structure shown in Figs. 12 and 13. by making the hole through the cli of slightly' greater diameter than. the

Vbo t on which `itis mounted, as indicated by the -dotted lines in Fig. 12.

` The latter forms, however, and that in Fig. 1,5, while they permit tilting lof. 'the blip, lievetheboltof'the radial strain. i

`Fig 141 illustrates.,that itis not requisite that the Clip shall'extndioVe-r 'and embace the edge of the-rim. In place-of lthe hookedV portion 43,.I may substitute an offset lug 47 fon the 4clip entering a pocket 48 in .the edge ff. theffrjm, or an other suitable/'connec- "tionbetween the c ip and rim which is ca- Poble of transmitting tothe `rim the oblique already described in deta'il.

place of a continuous flange about the edge of the rim opposite to the clips,`I may usea'plurality of keepers carried bythe same'retaining means'on which the detachable-clips are mounted. I 'have shown this typeof .rim in' Fi 15,4 in which thel b olts 49' at"4 one side" o the telly sudpport the keefers' 50, and at the other si e the det vshown and described.

. 12 and 13the'bqlt 44 is shown to theclips 41 described in connection Vwith Figs. 12 and 13.

In Fig. 16. I have shown. that the bolts 52 on which the keepers 53 aremounted may pass through openings 54 through the fixed wheel member of greater diameter than the bolts. In this case each keeper or clip 53 has a surface 55 ada ted to engage some portion ,of'the finedl w eel member, such as the extension of the felly band 56. The inward pull of the clip upon the rimis thus accomplished entirely b 1 the movement of said clip (carrying wit there is, as inthis view, no substantial enlargement of the bolt-hole in the `clip) toward the center of the wheel, orbyja com-y blination of this action with the cant or tlltmg of the clip. This construction is par- Having thus described my invention, I claim: y 4 If 1.
